Video: The freaky deaky "shoot first, focus later" camera

I'm fascinated by the concept, partly because it answers a question I've always had.

There's so much visual data in the average photo that's indecipherable, whether due to parts being out of focus, shot in poor light, and so forth. A bad pic is like a badly damaged hard drive, with only some of the "files" readable. Can't technology figure out a way to recover the unrecoverable data? Yep, it can.

A new survey on education reveals some surprising results when it comes to public versus private education.

On a five-point scale, the average rating a public school education received was 3.0. Next came home schooling with an average rating of 3.14, and then charter schools with an average rating of 3.41. Private Christian schools received an average rating of 3.69...

Star Trek's replicators were not only able to produce any food or products our far-off descendants wanted, they were also able to make it from any kind of waste products.

It was the ultimate recycling scenario, one that the new Ekocycle Cube 3D Printer hopes to emulate by using a new filament made in part from recycled plastic bottles. The Ekocycle printer will be available from Cubify for $1,200 later this year, and will use filament cartridges that contain at least three recycled 20 oz. PET plastic bottles, but the material still retains the flexibility and durability of standard 3D printer filament.

Tests Show Most Store Honey Isn't Honey

More than three-fourths of the honey sold in U.S. grocery stores isn't exactly what the bees produce, according to testing done for Food Safety News. The results show that the pollen frequently has been filtered out of products labeled "honey."

The removal of these microscopic particles from deep within a flower would make the nectar flunk the quality standards set by most of the world's food safety agencies. The food safety divisions of the World Health Organization, the European Commission and dozens of others also have ruled that without pollen there is no way to determine whether the honey came from legitimate and safe sources. In the U.S., the Food and Drug Administration says that any product that's been ultra-filtered and no longer contains pollen isn't honey. However, the FDA isn't checking honey sold here to see if it contains pollen.

Law Banning Cyber Charter Schools May Be Harming Education in Rural Tennessee

A report released by the Tennessee Center for Policy Research suggests the state's charter school law, which expressly prohibits the authorization of cyber charters, may be preventing thousands of rural students from improving their education.

According to the report, more than a quarter of Tennessee's population is considered rural by the U.S. Census Bureau. Only 11 percent of the adults living in rural Tennessee areas have graduated from college, compared to 23 percent of those living in urban areas.

Foster care associated with increased risk for STDs among adolescents

Spending time in the foster care system may up a child's chances of having at least one laboratory-confirmed STD by young adulthood.

Results also showed that girls who had been in foster care were more likely to report engaging in risky sexual behaviors, such as having sex with a casual partner, having sex for money or having vaginal intercourse. They were also more likely to report having their first sexual intercourse at a younger age and a higher number of lifetime partners than their peers.

Here are guidelines for length for ten types of content. Most of these are compiled from studies that analyzed the high-performers.

"It depends." What a totally unsatisfying answer. Of course it depends. But there are rules of thumb. There is research. We can analyze what works and draw conclusions. We can create guidelines, especially for things that are measurable. Like length.

Hackers Reveal Nasty New Car Attacks--With Me Behind The Wheel

A pair of Pentagon-funded hackers prove it]s possible to take control of your car with a few keystrokes. Time for Detroit to wake up.

Stomping on the brakes of a 3,500-pound Ford Escape that refuses to stop-or even slow down-produces a unique feeling of anxiety. In this case it also produces a deep groaning sound, like an angry water buffalo bellowing somewhere under the SUV's chassis. The more I pound the pedal, the louder the groan gets-along with the delighted cackling of the two hackers sitting behind me in the backseat. Luckily, all of this is happening at less than 5mph. So the Escape merely plows into a stand of 6-foot-high weeds growing in the abandoned parking lot of a South Bend, Ind. strip mall that Charlie Miller and Chris Valasek have chosen as the testing grounds for the day's experiments...

Children Sicker Now Than in Past, Harvard Report Says

The number of American children with chronic illnesses has quadrupled since the time when some of their parents were kids, portending more disability and higher health costs for a new generation of adults, a study estimates.

An almost fourfold increase in childhood obesity in the past three decades, twice the asthma rates since the 1980s, and a jump in the number of attention-deficit disorder cases are driving the growth of chronic illnesses, according to researchers at Harvard University in Boston. The report is published in a themed issue of the Journal of the American Medical Association focusing on children's health.

Harvard Geeks invent real lightsaber | The Libertarian Republic

The geeks at MIT and Harvard were playing with photons when they somehow managed to get the particles to "clump together" to form a molecule. They say it behaves just like a lightsaber.

Gizmodo interviewed them: "The physics of what's happening is similar to what we see in the movies," said one of the researchers. Lasers helped discover a new form of matter that blows photons through a cloud of rubidium atoms. When more than one photon was sent through the cloud, the particles began to cling together and form a molecule.
